摘　　要：目的探讨导致前置胎盘发生的高危因素及不同类型前置胎盘产前出血状况。方法采用回顾性病例对照研究设计,对比分析198例前置胎盘病例组和198例对照组有关危险因素,并比较不同胎盘类型的产科危险因素及孕34周前出血状况。结果产科高危因素在前置胎盘组与对照组之间比较差异有统计学意义(P<0.05),而在不同前置胎盘类型中比较差异无统计学意义(P>0.05);不同前置胎盘类型在孕34周前发生产前出血几率比较,差异无统计学意义(P>0.05)。结论产科高危因素与前置胎盘的形成有关,但与前置胎盘类型无关;前置胎盘类型并不能预测产前是否能发生突破性大出血。Objective To investigate the risk factors lead to the occurrence of placenta previa and antepartum hemorrhage between different types of placenta previa.Methods To comparatively analyze 198 cases of placenta previa patients and 198 patients in the control group on risk factors for bleeding before 34 weeks and compare different types of placenta obstetric risk factors and the incidence of antepartum haemorrhage.Results There were significantly differences in obstetric risk factors between placenta previa group and control group（P 0.05）,the difference was no statistically significant in the type of placenta previa（P 0.05）.The incidence of antepartum haemorrhage in the type of placenta previa showed no significant difference（P 0.05）.Conclusion Obstetric risk factors is related to placenta previa,but is not related to the types of placenta previa;the type of placenta previa is not associated with antepartum bleeding.
